‘M-x hide-lines’ written by MarkHulmeJones. It provides a function to quickly hide lines based on a regexp.

Does anyone knows why it doesn’t work in shell-script-mode?
Why not make it reversely hidden, i.e. when the Regxp is found ,the correspoended line will be preserved,while other will be hidden, I find this feature in Multieditor
the prefix arg (press C-u first, before the key for the hide-lines function) lets you do this. - MarkHulmeJones
I suggest the addition of the following two lines in the definition of “hide-matching-lines”, allowing the user to show all hidden areas giving an empty regexp for the normal call of the function. In this way there is no need to define yet another keystroke for “show-all-invisible” (which will presumably be used aprox. as many times as “hide-matching-lines” itself):
(interactive "MHide lines matching regexp: ") ;; --- addition --- (if (equal search-text "") (show-all-invisible) ;; else, the rest of the function definition follows
Another suggestion: it would be good to have some indicator in the mode line about having lines currently hidden.
